Ketosis occurs as a metabolic consequence of negative energy balance in post-calving lactating dairy cows. Metabolism of free fatty acids, released from adipose tissue, generates excessive amounts of acetoacetate (AcAc), β-hydroxybutyrate (BHB), and acetone (Ac) in the liver, which are released into the blood. The effects of ketone bodies on endothelial cells include increased rates of portal vein...
Elevated level of cellular lipid peroxidation can increase the incidence of vascular disease. The mechanism by which ketosis causes accelerated cellular damage and vascular disease in diabetes is not known. This study was undertaken to test the hypothesis that elevated levels of ketone bodies increase lipid peroxidation in endothelial cells. Human umbilical venous endothelial cells (HUVEC) were cultured...
